ELECTRICAL CURLING-IRON HEATER.

Application flied May 4, 1925'. Serial No. 27,694;

To all whom it may concern: l

Be it known that we, THEODORE S. Lo REN'ZE and Valiant: S. SCHMIDT, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and. useful Electrical Curling-Iron Heater, of which the following is a specification.

Our invention relates to improvements in electrical curling iron heaters and'more specifically to a curling heater having acontrol switch apart from the heating muffle.

The general object of the invention is to provide an electrical curling iron heater of improved construction, which is inexpensive to manufacture, eliicient from an operating standpoint, and neat in appearance.

- A more specific object is to provide a novel curling iron heater having an electrical control switch mounted within a sup- 1 porting base and operable from a convenient point outside of the base.

Further objects and advantages will be apparent from the following description.

In the accompanying drawings Fig. 1 is a front elevation partly in section of a curling iron heater embodying the features of our invention.

Fig. 2 is a sectional view taken along the plane of the line 22 of Fig. 1... Referring to the embodiment of the in vention illustrated in the drawings, represents a hollow rectangular base above which is supported an electrical heating muflle 11. Preferably the base is molded from insulating and heat resisting material and comprises a flat top wall 12 and a peripheral side wall 13. In the present in stance, ribs 14 formed along the longitudinal edges of the top serve toretain curling irons or other instruments placed upon the base.

The muflle 11 may be of any preferred shape or construction. It is shown in, the drawings as comprising two metal tubes 15 and 16 held together in concentric relation by end rings 17 The. inner tube 16 defines ,a central heating chamber 1 8 and is surrounded by a suitable electrical heating ele-.

ment 19 properly insulated from each of the tubes 15 and 16.

The muflle 11 is supported above the base 10- on two spaced apart standards 20. each having a central 20. Bolts 21- exvehientto operate, and neat and artistic in.

tending through the standards 20 fromthe under side of the base and threading into ported ininclined position relative to the 7 base.

The heating element 19. is connected to the source of power by insulated lead wires 22 which may enter the base 10 through a hole 22 infthe top .wall 12 and extend upwardly through a central opening 23 into the outer tube 15. Between the base 10 and the tube 15,the wires 22 are protected by a metal conduit 24. I

To control the current supply to the heating element 19, a snap switch 25 is interposed in one of the lead wires, 22. The switch shown herein comprises a swinging contact lever 26 mounted in a "frame 27 and adapted to close a circuit across two insulated terminals 28 connected respectively to the ends of the broken lead wire. 29 is anoperating lever pivoted in the frame and arranged to swing the lever 26.

' a curling iron heater which is inxepensive and durable in construction, simple and conappearance. The base being of insulatingmaterial effectually avoids any danger of' damageto the supporting surface on which the heater is placed, while increasing .the efiiciency'of the as such. Further.- more the construction is well adapted for the association therewith 'of the control switch with only its operating lever exposed to view, and that readily and conveniently accessible to effect the, control ofcur- 105 rentwflow without necessitating a severing :of the line connections by pulling a plug as has heretofore been necessary.

.We claim as our invention: 1. Anelectric'al curling iron heater liavstandards on the base, a heating muflle supported by said standards, lead wires extend ing through certain of the walls of the base a and connecting said muffle to a source of current, a switch controlling the flow of current to said muflie, said switch being located beneath the top wall of the base and between said depending supporting wall so as to be concealed Within the base, and an operating member for the switch projecting through the top wall of the base.

2. An electric curling iron heater comprising, a! base molded of heat insulating material and having a top wall and depending side portions providing supports for the top wall, a heating muflle, a pair of standards for supporting the opposite ends of said Inuflie above the base, one end of said base being extended beyond the heating muffle, and a currentcontrol switch enclosed within such extended portion and having an operating lever projecting through the base.

In testimony whereof we have hereunto aflixed our signatures.
